Urgent: Unable to create profile on ustraveldocs.com

I'm trying to book a visa stamping appointment in the chennai consulate for me (H1B) and my wife (F1). I created a profile for myself on ustraveldocs.com and added my wife as a family member. But then I realized that it did not let me choose the visa type for my wife. So, I deleted her from the list of family members. Now, when I try to create a separate login/profile for my wife, it says that the profile for the said person already exists. So, I'm completely stuck.

I'll be calling the call center when they open tomorrow for help. But if any of you have advice on how to handle this, please do let me know.
